Debian DLA-1055-1 : libgd2 security update
Medium Nessus Plugin ID 102440
SynopsisThe remote Debian host is missing a security update.
DescriptionMatviy Kotoniy reported that the gdImageCreateFromGifCtx() function used to load images from GIF format files in libgd2, a library for programmatic graphics creation and manipulation, does not zero stack allocated color map buffers before their use, which may result in information disclosure if a specially crafted file is processed.
For Debian 7 'Wheezy', these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u9.
We recommend that you upgrade your libgd2 packages.
